SPECIFICATION forming part of Letters Patent No. 622,941, dated April 11, 1899. Appncaion ned July 23,1898. 'serai No. 686,751. ci@ model.)

To all whom t may concern.-

Be it known that I, EUGENE AGUsTUs BURNS, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts,haveinvented certain new and useful Improvements in Lasts; and I do declare the following to be a full, clear, and exact description'of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The invention relates to that well-known class of lasts which are transversely divided to form a front and rear section, so as to permit the last to be longitudinally shortened when it is intended to withdraw it from the boot or shoe. In this way no unnecessary The sections are connected at their meeting faces by hingejoints, so that the rear or heel section may be turned up. The great desideratum is to keep this heel-section securely in place in the shoe by a yielding force, so that in withdrawing the last from the shoe the motion in the arc of a circle will be gradual as the front section In the drawings, A represents the rear or heel section, and B the front or toe section, and C the strap-hinge, which connects them together a little below the middle of the altitude of the last. This enables' the heelsection to turn on the pintle without friction against the back of the shoe, the rear of sectionA being made on a curve in the `usual manner. The straps c cof the hinge are preferably held by the screws d cl, while at each end of the pintle is arranged a reinforcement D, made of leather or rubber.

E is aspiral spring, whose ends are secured in opposite holes of the two sections, the face of section A being cut away to form an acute angle with the perpendicular face of section B. This allows section A to move on the hinge-pintle in the desired arc.

Having thus described all that is necessary to a full understanding of myinvention, what I claim as newr is- A shoe or boot last having the two hingeconnected separate parts A B provided with an intermediate angular space at the upper part, and across this space with a spiral spring E that holds the opposite faces apart; all arranged as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

`EUGENE AGUSTUS BURNS.
